Popcorn A student runs an experiment to test four differ-ent popcorn brands, recording the number of kernels left unpopped. She pops measured batches of each brand4 times, using the same popcorn popper and randomizing the order of the brands. After collecting her data and ana-lyzing the results, she reports that the F-ratio is 13.56. a) What are the null and alternative hypotheses?b) How many degrees of freedom does the treatment sumof squares have? How about the error sum of squares? c) Assuming that the conditions required for ANOVAare satisfied, what is the P-value? What would youconclude?d) What else about the data would you like to see in orderto check the assumptions and conditions?
